Passing arguments to an Expect script as variables

[piers]

Does anyone know how I can run a script with arguments and then use those arguments as variables in an Expect script?

So i would run $ myscript.exp thisuser thispass and then myscript.exp will be able to use thisuser and thispass as variables.

All the docs I can find for expect are really really old, does anybody else still use it?

You need to use lindex, try

set arg1 [lindex $argv 0]
set arg2 [lindex $argv 1]

send $arg1\n
send $arg2\n

I hope this helps,

From your tutorial i write a script for copy scp files between two servers by passing password as an arguments thanks a lot







first install expect

sudo apt-get install expect



then create copyremotefiles.sh




#!/usr/bin/expect -f

set from [lindex $argv 0]
set to [lindex $argv 1]
set pass [lindex $argv 2]

# connect via scp
spawn scp -r $from $to
#######################
expect {
-re ".*es.*o.*" {
exp_send "yes\r"
exp_continue
}
-re ".*sword.*" {
exp_send $pass\n
}
}
interact

Then change file permission

chmod 755 copyremotefiles.sh

now run

./copyremotefiles.sh /path/myfile.txt root@45.65.89.22:/home/lingesh/ PASSWORD_OF_REMOTE_SERVER


PASSWORD_OF_REMOTE_SERVER is root password of 45.65.89.22

Enjoy.....
